The condenser of the first embodiment is the axial flow type condenser being assemblied in steam turbine.As shown in Figure 3 and 4, container 11 is formed as the box shape of hollow to this condenser, and the one end at the first horizontal direction X is provided with inflow entrance 12, is linked with the exhaust chamber 14 of not shown steam turbine via middle casing 13 at this inflow entrance 12.Therefore, the steam S from the swirling flow of steam turbine discharges to exhaust chamber 14, flows into from inflow entrance 12 to container 11 along the first horizontal direction X via middle casing 13.
Container 11 is equipped with four cooling tube groups 21,22,23,24 in inside along the second horizontal direction Y, and the inflow direction (the first horizontal direction X) of this second horizontal direction Y and the steam S of the swirling flow flowed into from inflow entrance 12 is substantially orthogonal.These four cooling tube groups 21,22,23,24 configure in the way of separating predetermined distance along vertical.Each cooling tube group 21,22,23,24 is constituted along the second horizontal direction Y multiple cooling tubes arranged by container 11, and the end of each cooling tube is supported by each sidewall 11a of container 11, and pars intermedia is supported by multiple tube support plate 11b.Further, the end of each cooling tube of cooling tube group 21,22,23,24 connects with entrance hydroecium 25 and the outlet hydroecium 26 in the outside being arranged at each sidewall 11a.Entrance hydroecium 25 is linked with cooling water supplying pipe 27, and outlet hydroecium 26 is linked with cooling water drainage and goes out pipe 28.It addition, container 11 has air chamber 29 in the arranged outside of rear wall 11c, the air (non-condensing gas) that steam cools down and produces is assembled in container 11.Air chamber 29 is linked with air discharge duct 30.
Therefore, cooling water C flows into each cooling tube of cooling tube group 21,22,23,24 from cooling water supplying pipe 27 when supplying to entrance hydroecium 25.This cooling water C is flowed out to outlet hydroecium 26 by each cooling tube, and goes out pipe 28 by cooling water drainage and discharge.Now, steam S carries out heat exchange by contacting with each cooling tube of cooling tube group 21,22,23,24.That is, steam S cools down and condenses and become condensed water W, then falls and is stored in the bottom of container 11.On the other hand, the non-condensing gas G that steam S cools down and produces is gathered in air chamber 29, is discharged to outside by air discharge duct 30.
Hereinafter, the structure of cooling tube group 21,22,23,24 is described in detail.It should be noted that each cooling tube group 21,22,23,24 adopts same structure, therefore only cooling tube group 21 is especially described in detail.
Fig. 1 is the sketch of the cooling tube group of the condenser illustrating the first embodiment, and Fig. 2 is the major part enlarged drawing of cooling tube group.
As shown in Figure 1 and Figure 2, cooling tube group 21 is configured and configured in parallel in the way of separating predetermined distance along the second horizontal direction (paper orthogonal direction) by multiple cooling tubes 31, thus being formed as longer on the first horizontal direction X, and be formed as tapered shape towards the upstream side of the flow direction of steam S.That is, cooling tube group 21 is set as the size that the height (thickness) of the length ratio vertical of the first horizontal direction X is big.Cooling tube 31 is the cylindrical duct with predetermined outside diameter, and cooling tube 31 opposed in vertical configures in the way of the predetermined distance that staggers in the horizontal direction.That is, three adjacent cooling tubes 31 form base equilateral triangle in the horizontal direction, thus the height over width of this triangle is little.
Cooling tube group 21 becomes to have hollow bulb 32 along the first horizontal direction X-shaped in inside.This hollow bulb 32 has the first hollow bulb 32a in the downstream of the flow direction (the first horizontal direction X) being arranged on steam S and is set to the second hollow bulb 32b that the upstream side of the flow direction (the first horizontal direction X) from the first hollow bulb 32a to steam S extends.First hollow bulb 32a is formed as trapezoidal cross-section (triangular cross-section), and the long side direction (the second horizontal direction) along cooling tube 31 is arranged.Second hollow bulb 32b is formed towards the tapered rod shape of upstream side of the flow direction of steam S, and the long side direction (the second horizontal direction) along cooling tube 31 is arranged.First hollow bulb 32a and the second hollow bulb 32b connection.
The downstream end of the flow direction of the non-condensing gas discharge section 33 steam in cooling tube group 21 configures along the second horizontal direction.Non-condensing gas discharge section 33 is created as the casing of the hollow shape of rectangular section, has front face 33a, rear face 33b, upper surface portion 33c and lower face 33d.Further, front face 33a, upper surface portion 33c and the cooled pipe group 21 of lower face 33d beyond rear face (face) 33b are surrounded, and rear face (face) 33b exposes to outside.That is, non-condensing gas discharge section 33 is configured to rear face (face) 33b from cooling tube group 21 towards steam passage side, opposed with the internal face of the rear wall 11c of container 11.
It addition, non-condensing gas discharge section 33 is formed with peristome 34 at the front face 33a of hollow bulb 32 side.This peristome 34 is rounded and be the through hole of through front face 33a, configures in the way of separating predetermined distance in the second horizontal direction.It should be noted that peristome 34 both can be provided with 1 row in the second horizontal direction but it also may arranging more than 2 row, shape is also not necessarily limited to circle, it is also possible to be square, can also be slit in addition.
Partition member 35 is open from peristome 34 side of non-condensing gas discharge section 33 towards hollow bulb 32 side.This partition member 35 is made up of with lower demarcation strip 37 upper demarcation strip 36.Upper demarcation strip 36 configures along the second horizontal direction, and the top of the front face 33a of base end part and non-condensing gas discharge section 33 links.Lower demarcation strip 37 configures along the second horizontal direction, and the bottom of the front face 33a of base end part and non-condensing gas discharge section 33 links.Further, upper demarcation strip 36 connects with hollow bulb 32 with the lower respective leading section of demarcation strip 37.
Upper demarcation strip 36 extends towards hollow bulb 32 side upward with the angle of inclination of regulation.Lower demarcation strip 37 extends downwards towards hollow bulb 32 side with the angle of inclination of regulation.Therefore, partition member 35 is configured to the interval (distance) of upper demarcation strip 36 and lower demarcation strip 37 and increases towards hollow bulb 32 side.That is, upper demarcation strip 36 has the rake 36a on the top of the front face 33a being fixed on non-condensing gas discharge section 33 and links and the horizontal part 36b that connects with hollow bulb 32 with rake 36a.It addition, lower demarcation strip 37 has the rake 37a of the bottom of the front face 33a being fixed on non-condensing gas discharge section 33 and links and the horizontal part 37b that connects with hollow bulb 32 with rake 37a.Therefore, for partition member 35, opposed up and down by each rake 36a, 37a, thus the interval of upper demarcation strip 36 and lower demarcation strip 37 is gradually increased towards hollow bulb 32 side, opposed up and down by each horizontal part 36b, 37b, thus the interval of upper demarcation strip 36 and lower demarcation strip 37 is identical.
It addition, partition member 35 (upper demarcation strip 36 and lower demarcation strip 37) is open from non-condensing gas discharge section 33 towards hollow bulb 32 side, leading section connects with the first hollow bulb 32a of hollow bulb 32.Hollow bulb 32 is additionally provided with the 3rd hollow bulb 32c except the first hollow bulb 32a and the second hollow bulb 32b.3rd hollow bulb 32c be set to the front face 33a of non-condensing gas discharge section 33 faced by.It should be noted that, adjacent cooling tube in multiple cooling tubes 31 all separate same size and specified gap each other and to configure at equal intervals, hollow bulb 32 (32a, 32b, 32c) refers to the gap of adjacent cooling tube 31 gap each other or cooling tube 31 and other components (non-condensing gas discharge section 33, partition member 35 etc.), and other components gap each other is set to the region bigger than specified gap.
The cooling tube group 21 that so constitutes, hollow bulb 32, non-condensing gas discharge section 33 and partition member 35 relative to the centrage O1 of level be set on roll off the production line the shape of symmetry.Particularly, the thickness (highly) that cooling tube group 21 is divided into cooling tube group upper area 21A and cooling tube group lower area 21B, cooling tube group upper area 21A and cooling tube group lower area 21B relative to the hollow bulb 32 being centrally located on line O1 is set as identical.
It should be noted that the rear face 33b of the one end of connecting piece 38 and non-condensing gas discharge section 33 links, the air chamber 29 of the other end and the outside being arranged in container 11 links.Air discharge duct 30 is provided with vacuum pump 39.Therefore, by making vacuum pump 39 work such that it is able to make suction function in non-condensing gas discharge section 33 via air discharge duct 30, air chamber 29, connecting piece 38.
It addition, cooling tube group 21 is provided with the pallet 40 accepting the condensed water condensing and falling downwards.This pallet 40 configures along the second horizontal direction in the lower section of cooling tube group 21, is linked with not shown condensed water discharge pipe in end.Though it should be noted that this pallet 40 is preferably set to the length identical with the first horizontal direction X of cooling tube group 21, but swimming effluent further downward due to the flowing than steam S of the condensed water that falls and move, therefore can also omit or shorten side, leading section.
At this, the effect of the condenser of the first above-mentioned embodiment is illustrated.
As it is shown in figure 1, when the steam S of the swirling flow from steam turbine flows into container 11 from inflow entrance 12 along the first horizontal direction X, this steam S arrives each cooling tube group 21,22,23,24 and contacts with multiple cooling tubes 31.Then, by carrying out heat exchange between the cooling water C in this steam S and each cooling tube 31, steam S is cooled and condenses, and is formed as condensed water W and accumulates in the bottom of container 11.
Now, as shown in Figure 1 and Figure 2, steam S-phase flows into from above for the cooling tube group upper area 21A in cooling tube group 21, flows into from below relative to cooling tube group lower area 21B.At this, owing to cooling tube group upper area 21A is identical with the thickness of cooling tube group lower area 21B, therefore, it is possible to generate the condensed water of approximate equality in both.That is, non-condensing gas discharge section 33 has acted on negative pressure by the work of vacuum pump 39, utilizes partition member 35 to act on attractive to hollow bulb 32.Therefore, steam S is moved in hollow bulb 32 by cooling tube group 21, contacts with cooling tube 31 during this period, is cooled and condenses.
